Eco logical

If you ask the birds.
Those who pollute our air,
where the lungs are consumed,
the echo, of course, responds:
... man ... man ... man ...

And the humus of our ground,
that remains our bread pro
after a fire?
The echo, of course, responds:
... almost nothing ... almost nothing ...

What was the Sahara?
The Amazon is what?
A very uncertain future?
The echo, of course, responds:
... only the desert ... only the desert ...

What straight, clearing,
what's left, devastating,
predator to man?
The echo, of course, responds:
... only the pain ... the pain ... the pain ...

Which specifies the nature
to maintain its beauty
and soothe your pain?
The echo, of course, responds:
... more love ... love ... love ...
